Abstract
Based on strong research evidence, thyroid nodules in children and teenagers are more likely to be malignant than in adults. Based on strong research evidence, a history of ionizing radiation to the head or neck is an independent risk factor for the development of thyroid malignancies. There is strong research evidence, including a recent meta-analysis, supporting the use of fine-needle aspiration biopsy in the evaluation of all pediatric and adolescent patients presenting with a thyroid nodule. The surgical management and postoperative care of pediatric and adolescent patients who have well-differentiated thyroid carcinomas remains controversial, because the rarity of the disease limits the ability to conduct randomized, prospective research studies. Numerous studies have demonstrated that, despite presenting with more advanced disease, pediatric and adolescent patients with thyroid carcinoma have a higher survival rate than adults. The American Thyroid Association has issued strong evidence-based recommendations for the management of medullary thyroid carcinoma, including RET mutation testing and early prophylactic total thyroidectomy in children with high-risk mutations.

Features of acid–base balance of bone marrow
Lyudmila P Nikolaeva

Acta Medica International 2018 5(2):55-57

Context: Bone marrow (BM) pH has rarely been measured, and the long BM has barely been studied at all because intravital obtaining of the long BM is impossible due to the extreme strength of the long bone tissue. Aims: The study aimed to investigate the acid–base balance of the BM and to compare the acid–base properties of long BM and flat BM. Subjects and Methods: Forty flat BM samples were extracted by sternal puncture. Forty long BM samples were extracted from the femora in patients who had to have a limb amputated. A blood gas and acid–base status analyzer were used to determine pH. Results: Flat BM pH is similar to blood p; the long BM pH is acidic and ranges from 6.7 to 6.9. Hematopoietic stem cells occur in both acidic and slightly alkaline environments. The blood gas and acid–base status analyzer used in this study are suitable for determining the acid–base properties of BM. Conclusions: The acid–base status appears to be an important factor of stem cell differentiation. This paper can be of interest to biotechnologists and researchers who investigate possibilities to influence the differentiation and properties of the stem cells.

Persis Ann George, Anila Varkey, Adithya Nandan, Uday Venkat Mateti, Mundayat Gopalakrishnan, Rovin Mathew Theempalangad

Acta Medica International 2018 5(2):58-62

Aim: Postoperative atrial fibrillation (POAF) is one of the most commonly occurring complications after cardiac surgery. The study aims to determine the incidence of POAF and to analyze its pharmacological management in patients scheduled for cardiac surgery. Methodology: A prospective observational study was carried out for 6 months (October 2016 to March 2017) in cardiothoracic surgery. Drug therapy details by medication chart review and clinical review in patients who underwent coronary artery bypass graft, mitral valve replacement (MVR), and aortic valve replacement was carried out and analyzed for the incidence of POAF. The statistical analysis was performed using SPSS. Results: A total of 83 patients were recruited for this study. The POAF incidence was 18.07% with the highest incidence on the 2nd postoperative day. The mean age of patients with POAF was 49.40 ± 12.77 years. Rheumatic heart disease and alcohol were identified as the predisposing factors of POAF. The incidence of POAF was the highest following MVR (80%) than other cardiac surgeries. Patients who developed POAF had a longer length of hospitalization (median 9 vs. 7 days). Amiodarone, metoprolol, verapamil, atorvastatin, clopidogrel, and aspirin were the most frequently prescribed drugs for the management of POAF. Administration of metoprolol, nebivolol, atorvastatin, bisoprolol, metoprolol + atorvastatin + aspirin, and other combinations before cardiac surgery reduced the risk of developing POAF. Conclusion: The overall incidence of POAF was 18.07%. Amiodarone (13.3%), metoprolol (40%), verapamil (66.7%), aspirin (26.7%), clopidogrel (13.3%), and atorvastatin (20%) were found to be safe and effective in the treatment of POAF patients. 


Caregivers' awareness and perception of cardiopulmonary resuscitation: Our experience
Ibrahim Aliyu, Abdulsalam Mohammed, Zainab F Ibrahim

Acta Medica International 2018 5(2):63-68

Introduction: Adverse health-related events such as cardiac arrest can occur at any location: it is broadly classified as out-of-hospital or in-hospital cardiac arrest. The location of cardiac arrest however affects outcome; the actions of caregivers and bystanders may influence the outcome of witnessed out-of-hospital cardiac arrest; therefore, their knowledge of cardiopulmonary resuscitation (CPR) is relevant. Materials and Methods: This was a questionnaire-based cross-sectional study conducted at the Paediatric Outpatient Clinic and Paediatric Specialty Clinic of Aminu Kano Teaching Hospital. Results: There were 120 (33.3%) males and 240 (66.7%) females, with a male-to-female ratio of 1:2. Only 57 (15.8%) respondents were aware of CPR. However, 69 (19.2%) respondents were aware of chest compression. One hundred and twenty-nine (35.8%) respondents reported that they could perform mouth-to-mouth resuscitation on their own children; however, 66 (18.3%) respondents reported willingness to perform mouth-to-mouth resuscitation on another person's child if the need arose. Only 15 (4.2%) respondents had training on CPR. Six (40%) respondents were trained at school. However, caregivers in the chronic illness subgroup were more willing to perform mouth-to-mouth resuscitation. Caregivers of children with acute illnesses would use palm kernel oil to treat convulsion; however, those of the chronic illness group would mostly use herbs to treat convulsion; this observation was statistically significant (Fisher's exact test = 32.457, P = 0.00). Conclusion: There was poor awareness of CPR among respondents; furthermore, there was lack of willingness to perform CPR by most respondents on children.

Usha Kumari Chaudhary, Som Raj Mahajan, Monika Mahajan, Charu Sharma, Mukesh Sharma

Acta Medica International 2018 5(2):69-73

Background and Aims: Baska mask is a newly introduced membranous cuffed supraglottic device whereas I-gel is made up of thermoplastic elastomer, both suitably designed from the anatomical perspective of the airway. Settings and Design: We conducted randomized controlled comparative trial of the Baska mask versus I-gel in a patient undergoing laparoscopic cholecystectomy. Subjects and Methods: A total of 100 adult patients in the age group of 20–70 years undergoing elective laparoscopic cholecystectomy were randomly divided into two groups as follows: (1) Baska mask group and (2) I-gel group. The primary outcome was to compare oropharyngeal leak pressure (OLP) of Baska mask and I-gel groups. The secondary outcome was the ease of insertion and removal, number of attempts, insertion time, leak fraction, and laryngopharyngeal morbidity. Statistical Analysis Used: Demographic details were compared using the Chi-square and t-tests. Student's t-test for independent variables was used to compare means of data obtained. Results: Mean OLP was significantly higher in Baska mask group than I-gel group at insertion (29.54 ± 1.41 cm H2O vs. 23.16 ± 3.07 cm H2O, P = 0.02) and 30 min after insertion (33.54 ± 1.16 cm H2O vs. 25.97 ± 2.25 cm H2O, P = 0.001). Insertion time was 12.33 ± 2.61 s with Baska mask and 11.31 ± 1.84 s with I-gel (P = 0.02). Insertion was very easy in 58% of patients in Baska mask and 76% of patients in I-gel (P = 0.03). The leak fraction of Baska mask was significantly less than I-gel (3.56 ± 3.6 vs. 7.16 ± 2.45, P = 0.01). Laryngopharyngeal morbidity was comparable in the two groups. Conclusion: Baska mask is more effective in providing greater OLP compared to I-gel without any increase in laryngopharyngeal morbidity.

Acta Medica International 2018 5(2):74-78

Aims: The aim of this study was to evaluate the complexity of the chromosomal abnormalities in multiple myeloma (MM) cases and to correlate the findings with the previous reported cases. Materials and Methods: Bone marrow samples were obtained from patients with MM and sent for cytogenetic study. The patient's details were logged and the cytogenetic test was performed. The karyotypes were analyzed and interpreted as per the standard guidelines. Results: Of the compiled data of cases from 2013 to 2016, 34 patients were diagnosed with MM. About 15% were below the age of 50, maximum patients were between ages of 61 and 70 years (50%). There were 25 male and 9 female. Twenty-one cases had normal karyotypes and few cases showed structural rearrangements and numerical abnormalities. Conclusions: From the data compiled, only a total of 34 cases were positive for MM, indicating that the disease is quite rare in our population. It has been previously reported that the disease usually occurs in people over the age of 50 years, however, in this study, 5 (15%) were below the age of 50 indicating that MM can affect the age group below 50 years as well. The numerical, structural abnormalities and few clonal abnormalities observed in our study added a few more to the previously reported abnormalities. However, the interesting finding of our study was a case with a combination of clones of hypodiploidy, hyperdiploidy, hypotetraploidy, and hypertetraploidy which was in contrary to the reported literatures, which were only one type of ploidy were observed. Thus, the heterogeneity and complexity of the chromosomal abnormalities in MM and the challenge in staging the disease have been proven in our study.

Shuvendu Roy, Ashish K Simalti, Bindu T Nair

Acta Medica International 2018 5(2):79-83

Background: The World Health Organization defines exclusive breastfeeding (EBF) as giving baby only breast milk for the first 6 months without adding any additional drink including water or food. We undertook this study with an objective to assess the prevalence of breastfeeding among mothers in North Indian setting. Aims: The aims of this study were to assess the prevalence of EBF among mothers attending a well-baby clinic and to look for variable significantly impacting probability of breastfeeding and assessing the challenges faced and existing knowledge regarding breastfeeding. Materials and Methods: This was a questionnaire-based one-point survey to assess the prevalence of EBF. The questionnaire was based on the review of literature and included parameters considered significant by various studies. Mother's knowledge regarding breastfeeding was assessed by another questionnaire. Results: A total of 970 mothers were approached who visited immunization center and well-baby clinic during the study. After taking out those who were unwilling and did not meet the criteria, we had 634 mothers who participated in our study. They were divided into two groups based on whether they exclusive breastfed their babies for 6 months or not. Comparison of both these groups revealed breastfeeding counseling to be the most important variable. Statistical Analysis Used: It is a cross-sectional type of study with a questionnaire-based one-point survey. The minimum sample size required was calculated using Daniel's formula: n = z2pq/d. Consequent sampling was done. Chi-square test for independence was done to assess the association between both the groups for all the parameters recorded. Conclusions: All mothers were aware that breast milk is beneficial for their baby; however, the biggest problem was anxiety regarding the adequacy of their breast milk. There is also need for a widespread campaign related to harm done by prelacteals and substitutes of breast milk including cow milk.

Exercise-induced bronchial asthma (EIBA) or exercise-induced bronchial spasm is all terms that describe the phenomenon of transient obstruction of the bronchi after intensive physical stress. This article presents the recommendations about the rational administration of pharmacological and nonpharmacological methods of treatment of EIBA that in the majority of cases enables to provide considerable control over the disease without limitation of the physical activity of patients.


Penile entrapment: A case where innovation is the need of the hour
Gajanan Shripad Bhat

Acta Medica International 2018 5(2):90-91

Penile entrapment is a rare and unique condition requiring urgent decompression to preserve the organ function and prevent complications. There is no universal method that is applicable to all cases as there are hardly any guidelines. Management of a 35-year-old male who presented to our emergency room with a metal ring around his penis has been described here. The case report highlights the need to devise one's own method to decompress the entrapped penis based on the available technology and manpower on hand in a given situation.

Yasemin Çoban, Dinçer Yildizdas, Özden Özgür Horoz, Nagehan Aslan, Didar Arslan

Acta Medica International 2018 5(2):92-94

Phenobarbital continues to be widely used in childhood epilepsy. Incorrect drug prescription can sometimes lead to intoxication, particularly in young children. A 40-month-old female infant presented to our emergency department due to failure to awaken. The patient was assessed in terms of etiology of coma, and her history revealed that she had been given a 100 mg phenobarbital pill instead of 15 mg. Her blood phenobarbital level was high (>80 mg/dl). At physical examination, her Glasgow coma score was 6, the pupils were isochoric, pupillary light reflex was bilateral positive, deep tendon reflexes were absent, respiration was superficial, and pulmonary bilateral diffuse secretory rales were present, and the patient was intubated. Continuous venovenous hemodiafiltration (CVVHDF) was performed due to prolonged coma, intubation, and potentially fatal phenobarbital level. Blood phenobarbital levels at 4 and 12 h improved to >80 and 33.4 mg/dl, and the patient was extubated at 14 h. CVVHDF was effective in intoxication despite long-acting barbiturate phenobarbital not binding to protein. We think that this is a useful method capable of use in phenobarbital intoxications.

Obstructive sleep-disordered breathing in children: Impact on the developing brain
Lisa M Walter, Rosemary S C Horne

Pediatric Respirology and Critical Care Medicine 2018 2(4):58-64

Obstructive sleep-disordered breathing (SDB) affects up to 11% of children and forms a continuum of severity ranging from primary snoring to obstructive sleep apnea. Children with SDB exhibit significant neurocognitive and cardiovascular dysfunction, which is associated with repetitive hypoxia and sleep fragmentation that characterize the condition. We reviewed the recent literature pertaining to the effect of SDB on the brain in children. These include studies that utilized near-infrared spectroscopy to determine cerebral oxygenation and structural and functional magnetic resonance imaging (MRI) of the brain. Studies have identified that the effect of SDB on cerebral oxygenation in children is minimal and not clinically significant. There are conflicting reports on the association between the measures of cerebral oxygenation and peripheral arterial oxygen saturation (SpO2), and further research needs to be conducted to elucidate the relationship between peripheral SpO2, cerebral oxygenation, and SDB in children. MRI studies have reported significant structural and functional changes to the brains of children with SDB, in brain regions associated with neurocognition, behavior, and autonomic function. These include reduced white and gray matter and structural changes to a multitude of brain areas including, but not limited to, the hippocampus, cortex, amygdala, insula, thalamus, cerebellum, and basal ganglia. These studies utilize a variety of MRI techniques to address different research questions, but contribute to the gradually developing picture of the adverse effects of SDB on the brain in children.

Pediatric Respirology and Critical Care Medicine 2018 2(4):65-72

Objective: The objective of this study is to compare the performance of a modified Pediatric Risk of Mortality (PRISM) III model with the original PRISM III in prediction of mortality risk in a Thailand pediatric intensive care unit (PICU). Subjects and Methods: Children aged 1 month to 18 years who stayed in the PICU for more than 8 h during November 2013 to December 2016 were included in the study. Results: The medical records of 1175 PICU patients were included in the analysis. The patients were randomly split into two equal groups: a development (n = 588) and a validation (n = 587) sample. A modified PRISM III model was derived from the original PRISM III by omitting arterial blood gas parameters and adding selected clinical variables. The model was developed using a multiple logistic regression model on the development sample and assessed using the area under the curve (AUC) obtained from a receiver operating characteristic curve. The modified PRISM III scores were significantly higher in nonsurvivors (median = 9, interquartile range [IQR] = 4 − 13) compared to survivors (median = 2, IQR = 0 − 5). The modified PRISM III model had similar discriminative performances compared to the original PRISM III in predicting 2-day mortality (AUC: 0.874 vs. 0.873), 7-day mortality (AUC: 0.851 vs. 0.851) and overall mortality (AUC: 0.845 vs. 0.956). The modified PRISM III model was calibrated in the validation sample, and the standardized mortality ratios (SMRs) were similar. Conclusions: The performance of a modified PRISM III model in predicting mortality risk was comparable to the original PRISM III. Both had similar discriminative performance and SMR for overall mortality prediction in a PICU. 


Pulmonary function abnormalities in Nigerian children with sickle cell anaemia: Prevalence, pattern and predictive factors
Bankole Peter Kuti, Samuel Ademola Adegoke

Pediatric Respirology and Critical Care Medicine 2018 2(4):73-79

Background: Advances in care of children with sickle cell anaemia (SCA) have increased their chances of survival to adolescence and adulthood though this is often associated with multi-organ system pathologies including lung dysfunctions. This study aimed to determine the prevalence, pattern and factors associated with pulmonary function abnormalities in Nigerian children with SCA. Methods: Pulmonary functions of 104 children with SCA in steady state and 104 age- and sex-matched haemoglobin AA controls aged 6 to 16 years at the Wesley Guild Hospital, Ilesa Nigeria, were assessed using Spirolab III (Medical International Research, Italy) spirometer following standard protocol. Socio-demographic characteristics, nutritional status and pulmonary function parameters of these children were compared, and the predictive factors of pulmonary function abnormalities in SCA children were determined using binary logistic regression. Results: SCA children had lower lung volumes and capacities and higher prevalence of pulmonary function abnormalities compared to controls, and a restrictive ventilatory pattern (22.1%) was the most predominant form. Adolescent age, previous acute chest syndrome (ACS), repeated painful crises and multiple hospitalisations in the previous year were significantly associated with pulmonary function abnormalities (P < 0.05). Only adolescent age group (odds ratio [OR] = 3.738; 95% confidence interval [CI] = 1.480–9.440; P = 0.005) and previous ACS (OR = 8.500; 95% CI = 2.044–12.959; P = 0.044) independently predicted pulmonary function impairments among the SCA children. Conclusion: SCA predisposes children to pulmonary dysfunction, particularly during adolescent years and in those with ACS, multiple crises and hospitalisations. Routine pulmonary function assessment in these children will facilitate early recognition and prompt management.
